Description

Science and Math Informal Learning Educators (SMILE) Abstract:

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer. The pebbles are left in the beaker, the wood is caught by the strainer, and the salt stays dissolved in the water. The main idea is that different physical properties of the components can be used for separating them, and that evaporation can be used to isolate a solute from a solution. This activity is currently used in the Nature of Matter Unit in OMSI's Chemistry Lab. Cost estimates are per 100 learners.
